technical field

The present application relates to the technical field of communication, and more specifically, to a communication method and device.

Background technique

In some cases, a cell serving a terminal (hereinafter referred to as "serving cell") needs to be handed over from one cell to another. Specifically, the base station will send the measurement configuration to the terminal. The terminal may measure the cell according to the measurement configuration, and determine whether to report the measurement result according to the trigger condition. If the measurement result of a certain cell satisfies the trigger condition, the terminal may send the measurement result of the cell to the base station. The base station makes a judgment according to the measurement result reported by the terminal to determine whether to hand over the serving cell of the terminal from one cell to another.

However, in some cases, the cell that first triggers reporting of the measurement result may not be a suitable cell. Therefore, the cell to which the terminal needs to be handed over to, selected by the base station, may not be a suitable cell. Therefore, the current technical solution may cause the terminal to fail to switch to a suitable cell during the handover process.

101. Determine whether there is a first cell that satisfies a reporting trigger condition.

If the first cell exists, step 102 is performed; if the first cell does not exist, the process ends.

It can be understood that there may be multiple trigger conditions that satisfy the report.

In some embodiments, step 102 may be performed as long as it is determined that a cell satisfies the reporting trigger condition. For example, assuming that the measurement event is A4 and the terminal has 6 neighboring cells, it is sequentially judged whether neighboring cells 1 to 6 meet the reporting trigger conditions. In other words, it is first judged whether the neighboring cell 1 satisfies the reporting trigger condition, and then judges whether the neighboring cell 2 satisfies the reporting trigger condition, and so on. If it is determined that neighboring cells 1 and 2 do not meet the reporting trigger conditions and neighboring cell 3 meets the reporting triggering conditions, step 102 can be performed without continuing to judge whether neighboring cells 4 to 6 meet the reporting triggering conditions. Optionally, in some other embodiments, step 102 may also be performed after all cells are judged and it is determined that there are cells satisfying the reporting trigger condition.

The specific process of determining whether there is a cell satisfying the trigger condition can refer to the existing agreement, and only a brief description will be given below. The terminal may determine whether the first cell exists through the following steps.

Step 1, determine cell quality.

Optionally, in some embodiments, the cell quality can be characterized by the average value of the beam qualities of K beams in the cell, and the beam qualities of the K beams are all greater than the preset beam threshold, where K is greater than or equal to 1 positive integer. If the number of beams with beam quality greater than the preset beam threshold in a cell is greater than K, K beams can be selected from the beams greater than K, and the average value of the K beams can be taken as the cell quality of the cell. The selected K beams may be the K beams with the highest beam quality, or the K beams with the lowest beam quality greater than the preset beam threshold, or K beams selected randomly, or selected according to other methods The number of K beams is not limited in this embodiment of the present application. If the number of beams with beam quality greater than the preset beam threshold in a cell is less than K, the cell quality of the cell is the average of all beam qualities in the cell with beam quality greater than the preset beam threshold. The average value of the beam quality may be one of an arithmetic average value, a geometric average value, a weighted average value, and the like, which is not limited in this embodiment of the present application. The beam quality may be represented by reference signal receiving power (reference signal receiving power, RSRP) or reference signal receiving quality (reference signal receiving quality, RSRQ).

Optionally, in some other embodiments, when determining the cell quality of a cell, the average value of the beam qualities of K beams in the cell may be determined first, and then layer 3 filtering is performed on the average value of the beam qualities of the K beams, The value obtained after layer 3 filtering is the cell quality of the cell. The beam qualities of the K beams are all greater than the preset beam threshold. Similarly, if the number of beams with beam quality greater than the preset beam threshold in a cell is greater than K, K beams may be selected from the beams greater than K, and the average value of the K beams may be taken as the cell quality of the cell. The selected K beams may be the K beams with the highest beam quality, or the K beams with the lowest beam quality greater than the preset beam threshold, or K beams selected randomly, or selected according to other methods The number of K beams is not limited in this embodiment of the present application. If the number of beams with beam quality greater than the preset beam threshold in a cell is less than K, the cell quality of the cell is the average of all beam qualities in the cell with beam quality greater than the preset beam threshold. The average value of the beam quality may be one of an arithmetic average value, a geometric average value, a weighted average value, and the like, which is not limited in this embodiment of the present application.

The value of K used in step 1 and the preset beam threshold may be received from the base station.

Step 2: Determine whether there is a cell satisfying the trigger condition according to the cell quality and the trigger threshold.

Optionally, in some embodiments, the cell quality may be directly compared with the trigger threshold. If the cell quality of a cell is greater than the trigger threshold, the cell is a cell that satisfies the trigger condition. The trigger threshold may be a trigger threshold indicated by the base station, or a trigger threshold determined by the terminal itself. For example, if the cell quality of a cell is -59dBm and the trigger threshold is -61dBM, then the cell is a cell meeting the preset condition.

Optionally, in other embodiments, the adjusted cell quality may be determined first, and then whether the cell satisfies the trigger condition is determined according to the adjusted cell quality. The adjusted cell quality can be determined according to the measurement event. Measurement events may be indicated by the base station.

For example, if the measurement event is A3, the adjusted cell quality can be determined according to the following formula:

Q=Mn+Ofn+Ocn-Hys, (Formula 1.1)

Where Q represents the adjusted cell quality of a cell, Mn represents the cell quality of the cell, Ofn represents the frequency-level offset, Ocn represents the cell-level offset, and Hys represents the hysteresis.

Determine the trigger threshold according to the following formula:

T_Thresh=Mp+Ofp+Ocp+Off, (Formula 1.2)

T_Thresh represents the trigger threshold, and Mp represents the cell quality of the primary serving cell of the primary base station of the terminal or the primary serving cell of the secondary base station of the terminal without any offset. Ocp denotes a cell-level offset. Off represents an offset value. Ocn has the same meaning as Ocn in Formula 1.1.

If the adjusted cell quality of a cell is greater than the trigger threshold, the cell is a cell that satisfies the reporting trigger condition (that is, the first cell). Those skilled in the art can understand that the adjusted cell quality compared with the trigger threshold in the measurement event A3 is the adjusted cell quality of the neighboring cell.

As another example, if the measurement event is A4, the adjusted cell quality can be determined according to formula 1.1. If the adjusted cell quality of a cell is greater than the trigger threshold, the cell is a cell that satisfies the reporting trigger condition (that is, the first cell). The trigger threshold is indicated by the base station. In other words, the trigger threshold is received from the base station. Those skilled in the art can understand that the adjusted cell quality compared with the trigger threshold in the measurement event A4 is the adjusted cell quality of the neighboring cell.

As another example, if the measurement event is A5 measurement, the adjusted cell quality can be determined according to formula 1.1. Determine the adjusted cell quality of the primary serving cell of the primary base station of the terminal or the primary serving cell of the secondary base station of the terminal according to the following formula:

Q_Mp=Mp+Hys, (Formula 1.3)

Wherein, Q_MP represents the adjusted cell quality of the primary serving cell of the primary base station of the terminal or the primary serving cell of the secondary base station of the terminal, and Mp represents the primary serving cell of the primary base station of the terminal or the primary serving cell of the secondary base station of the terminal without adding any Offset cell quality, Hys is hysteresis.

Further, if the measurement event is A5, the trigger threshold may include a first trigger threshold and a second trigger threshold, and the first trigger threshold and the second trigger threshold are indicated by the base station.

If the adjusted cell quality of the primary serving cell of the primary base station of the terminal or the primary serving cell of the secondary base station of the terminal is less than the first preset threshold and the adjusted cell quality of a cell is greater than the second trigger threshold, then the cell is A cell that satisfies the reporting trigger condition (that is, the first cell). Those skilled in the art can understand that the adjusted cell quality compared with the second trigger threshold in the measurement event A5 is the adjusted cell quality of the neighboring cell.

As another example, if the measurement event is A6 measurement, the adjusted cell quality can be determined according to the following formula:

Q=Mn+Ocn-Hys, (Formula 1.4)

Where Q represents the adjusted cell quality of a cell, Mn represents the cell quality of the cell, Ocn represents the cell-level offset, and Hys represents the hysteresis.

Determine the trigger threshold according to the following formula:

T_Thresh=Ms+Ocs+Off, (Formula 1.5)

Where T_Thresh represents the trigger threshold, and Ms represents the cell quality of the serving cell of the terminal without considering any offset. Ocs represents the cell-level offset of the serving cell. Off represents an offset value.

If the adjusted cell quality of a cell is greater than the trigger threshold, the cell is a cell that satisfies the reporting trigger condition (that is, the first cell). Those skilled in the art can understand that the adjusted cell quality compared with the trigger threshold in the measurement event A6 is the adjusted cell quality of the neighboring cell.

In formula 1.1 to formula 1.5, the value of any one or more in the parameter (for example, Ofn, Ocn, Hys etc.) except Mn, Mp and Ms can be 0.

Optionally, in some embodiments, the cell quality (or adjusted cell quality) of all cells of the terminal may be determined first, and then the cell quality (or adjusted cell quality) of all cells and the trigger threshold A comparison is made to determine whether there is a cell that satisfies the trigger condition.

Optionally, in other embodiments, after the cell quality (or adjusted cell quality) of a cell is determined, compare the cell quality (or adjusted cell quality) of the cell with the trigger threshold. Determine whether there is a cell satisfying the trigger condition.

In the embodiment shown in FIG. 1 , the cells measured by the terminal belong to the same MO or cells in different MOs. In a possible manner, each time the terminal reports the measurement results of cells belonging to the same MO.

The base station will configure an MO number for all cells in the same MO. Cells belonging to different MOs have different MO numbers. When instructing the terminal to perform cell measurement, the base station will indicate the MO number to the terminal. The terminal can measure the corresponding cell according to the MO number. In some cases, the base station may instruct the terminal to measure cells in one MO at a time. In other words, the measurement instruction sent by the base station to the terminal will only carry one MO number. In other cases, the base station may also instruct the terminal to measure cells in two or more MOs at one time. In other words, the measurement instruction sent by the base station to the terminal may carry two or more numbers of MOs. In this case, when reporting the measurement results, the terminal may report the measurement results of the cells belonging to different MOs to the base station respectively. For example, the base station instructs the terminal to measure the cell in MO A and the cell in MO B respectively. The terminal may send the measurement result of the cell in MO A to the base station through an uplink message, and send the measurement result of the cell in MO B to the base station through another uplink message. It can be seen that during multi-MO measurement, although the terminal receives multiple MO numbers at the same time, the method of measuring cells and reporting cell measurement results is the same as that of single-MO measurement.

102. Determine a target cell according to measured measurement results and preset values of N cells, where N is a positive integer greater than or equal to 1.

It can be understood that, in this embodiment of the present application, the measurement results of all or part of the N cells may be used to determine the target cell.

Optionally, in some embodiments, the preset value may be preset in the terminal. In other words, the terminal can directly use the saved presets.

Optionally, in some other embodiments, the method may further include: receiving a measurement configuration sent by the base station, where the measurement configuration includes the preset value. In other words, before step 102, the preset value sent by the base station may also be received.

Optionally, in some embodiments, the measurement configuration may simultaneously carry the preset value, the value of K, the preset beam threshold, and the trigger threshold, which can save signaling overhead. Optionally, in some other embodiments, the preset value can be carried by one message, and the value of K, the preset beam threshold and the trigger threshold can be carried by another message, so that there is no need to change the message already stipulated in the existing protocol what is carried.

Optionally, in some embodiments, the N cells include the serving cell of the terminal and neighboring cells of the serving cell.

Optionally, in some other embodiments, the N cells include neighboring cells of the serving cell of the terminal. In other words, the serving cell of the terminal may not be included in the N cells.

Optionally, in some embodiments, the preset value is a first preset value, and determining the target cell according to the measured measurement results of the N cells and the preset value includes: The cell whose absolute value of the difference between the quality and the cell quality of the second cell is smaller than the first preset value is determined as the target cell, wherein the second cell is a cell with the best cell quality among the N cells.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -60dBm and -59.5dBm respectively. It can be seen that the cell quality of cell 3 is the maximum value of the six cell qualities. Assume that the first preset value is 2dBm. The difference between the maximum value of cell quality and the first preset value is -61dBm. In this way, the cell qualities of cell 3, cell 5, and cell 6 are all greater than -61 dBm. Therefore, the target cell includes cell 3 , cell 5 and cell 6 .

Optionally, in some embodiments, the target cell can be the second cell. In other words, except for the cell with the maximum cell quality among the N cells, the absolute value of the difference between the cell quality of the other cell and the cell quality of the second cell is smaller than the first preset value.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -62dBm and -63.5dBm respectively. It can be seen that the cell quality of cell 3 is the maximum value of the six cell qualities. Assume that the first preset value is 2dBm. The difference between the maximum value of cell quality and the first preset value is -61dBm. In this way, only the absolute value of the difference between the cell quality of cell 3 and the maximum value of the cell quality is less than 2 dBm. Therefore, the target cell only includes cell 3 .

Optionally, in some embodiments, the preset value is a first preset value, and determining the target cell according to the measured measurement results of the N cells and the preset value includes: The cell whose absolute value of the difference between the quality and the cell quality of the second cell is less than or equal to the first preset value is determined as the target cell, wherein the second cell is a cell with the best cell quality among the N cells.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. Assume that the cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -61dBm and -59.5dBm respectively. It can be seen that the cell quality of cell 3 is the maximum value of the six cell qualities. Assume that the first preset value is 2dBm. The difference between the maximum value of cell quality and the first preset value is -61dBm. In this way, the cell qualities of cell 3, cell 5, and cell 6 are all greater than -61 dBm. Therefore, the target cell includes cell 3 , cell 5 and cell 6 .

Optionally, in some embodiments, the preset value is a second preset value, and determining the target cell according to the measured measurement results of the N cells and the preset value includes: determining that each of the N cells The number of good beams in the cell, where the good beam is a beam whose beam quality is greater than the good beam threshold; determine the maximum value of the number of good beams in the N cells; the maximum value of the number of good beams in the N cells and the number of good beams The cell whose absolute value of the difference is smaller than the second preset value is determined as the target cell.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. The numbers of good beams of the six cells are 5, 1, 2, 4, 5, and 4, respectively. In this case, the maximum number of good beams is five. If the second preset value is 2, then the difference between the maximum number of good beams and the second preset value is 3. It can be seen that the number of good beams in cell 1, the number of good beams in cell 4, the number of good beams in cell 5, and the number of good beams in cell 6 are all greater than three. Therefore, the target cell includes cell 1 , cell 4 , cell 5 and cell 6 .

It can be understood that, in some cases, only the cell whose number of good beams is the maximum may have the number of good beams greater than the difference between the maximum number of good beams and the second preset value. In this case, the target cell only includes the cell with the largest value of the number of good beams.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. The numbers of good beams of the six cells are 5, 1, 2, 2, 1, and 2, respectively. In this case, the maximum number of good beams is five. If the second preset value is 2, then the difference between the maximum number of good beams and the second preset value is 3. It can be seen that only the number of good beams of cell 1 is greater than 3. Therefore, the target cell only includes cell 1.

Optionally, in some embodiments, the preset value is a second preset value, and determining the target cell according to the measured measurement results of the N cells and the preset value includes: determining that each of the N cells The number of good beams in the cell, where the good beam is a beam whose beam quality is greater than the good beam threshold; determine the maximum value of the number of good beams in the N cells; the maximum value of the number of good beams in the N cells and the number of good beams The cell whose absolute value of the difference is less than or equal to the second preset value is determined as the target cell.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. The numbers of good beams of the six cells are 5, 1, 2, 4, 3, and 4, respectively. In this case, the maximum number of good beams is five. If the second preset value is 2, then the difference between the maximum number of good beams and the second preset value is 3. It can be seen that the number of good beams in cell 1, the number of good beams in cell 4, the number of good beams in cell 5, and the number of good beams in cell 6 are all greater than three. Therefore, the target cell includes cell 1 , cell 4 , cell 5 and cell 6 .

Optionally, in some embodiments, the value of the good beam threshold may be the same as the value of the preset beam threshold in the trigger condition. In other words, the preset beam threshold in the trigger condition is the good beam threshold.

Optionally, in some other embodiments, the value of the threshold of the good beam may be different from the value of the preset beam threshold in the trigger condition. The base station can indicate the good beam threshold to the terminal through the measurement configuration.

Optionally, in some embodiments, the preset value is a third preset value, and determining the target cell according to the measured measurement results of the N cells and the preset value includes: determining the N cells according to the measurement event The adjusted cell quality of each cell in the cells; the cell whose absolute value of the difference between the adjusted cell quality and the trigger threshold among the N cells is smaller than the third preset value is determined as the target cell.

The method for determining the adjusted cell quality used when determining the target cell is the same as the method used for determining whether the cell quality meets the trigger condition. The trigger threshold is a trigger threshold used when determining whether the cell quality meets the trigger condition.

For example, if the measurement event is A3, the adjusted cell quality of each of the N cells can be determined according to formula 1.1. The trigger threshold can be determined according to formula 1.2. If the N cells include the serving cell of the terminal, the adjusted cell quality of the serving cell may also be determined according to formula 1.1.

For another example, if the measurement event is A4, the adjusted cell quality of each of the N cells may be determined according to Formula 1.1, and the trigger threshold may be received from the base station. If the N cells include the serving cell of the terminal, the adjusted cell quality of the serving cell may also be determined according to formula 1.1.

For another example, if the measurement event is A5, the adjusted cell quality of each of the N cells can be determined according to formula 1.1, the trigger threshold is the second trigger threshold, and the second trigger threshold can be received from the base station of. If the N cells include the serving cell of the terminal, the adjusted cell quality of the serving cell may also be determined according to formula 1.1.

For another example, if the measurement event is A6, the adjusted cell quality of each of the N cells can be determined according to Formula 1.4. The trigger threshold can be determined according to formula 1.5. If the N cells include the serving cell of the terminal, the adjusted cell quality of the serving cell may also be determined according to formula 1.4.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the adjusted cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -60dBm and -59.5dBm respectively. Assuming that the trigger threshold is -59dBm and the third preset value is 2dBm, the difference between the trigger threshold and the third preset value is -61dBm. In this way, the cell qualities of cell 3, cell 5, and cell 6 are all greater than -61 dBm. Therefore, the target cell includes cell 3 , cell 5 and cell 6 .

Optionally, in some embodiments, the preset value is a third preset value, and determining the target cell according to the measurement results of each of the N cells and preset conditions includes: determining according to a measurement event The adjusted cell quality of each of the N cells; the cell whose absolute value of the difference between the adjusted cell quality and the trigger threshold of the N cells is less than or equal to the third preset value is determined as the target cell .

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the adjusted cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -61dBm and -59.5dBm respectively. Assuming that the trigger threshold is -59dBm and the third preset value is 2dBm, the difference between the trigger threshold and the third preset value is -61dBm. In this way, the cell qualities of cell 3, cell 5, and cell 6 are all greater than -61 dBm. Therefore, the target cell includes cell 3 , cell 5 and cell 6 .

Optionally, in some embodiments, the preset value is the quality threshold of the target cell, and determining the target cell according to the measured measurement results of the N cells and the preset value includes: determining the target cell among the N cells according to the measurement event The adjusted cell quality of each cell; and the cell whose adjusted cell quality is greater than the preset target cell threshold is determined as the target cell.

The method for determining the adjusted cell quality is the same as the method for determining the adjusted cell quality in step 102 .

For example, if the measurement event is A3, the adjusted cell quality of each of the N cells can be determined according to formula 1.1. If the N cells include the serving cell of the terminal, the adjusted cell quality of the serving cell may also be determined according to formula 1.1.

For another example, if the measurement event is A4, the adjusted cell quality of each of the N cells can be determined according to formula 1.1. If the N cells include the serving cell of the terminal, the adjusted cell quality of the serving cell may also be determined according to formula 1.1.

For another example, if the measurement event is A5, the adjusted cell quality of each of the N cells may be determined according to Formula 1.1. If the N cells include the serving cell of the terminal, the adjusted cell quality of the serving cell may also be determined according to formula 1.1.

For another example, if the measurement event is A6, the adjusted cell quality of each of the N cells can be determined according to Formula 1.4. If the N cells include the serving cell of the terminal, the adjusted cell quality of the serving cell may also be determined according to formula 1.4.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the adjusted cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -60dBm and -59.5dBm respectively. Assuming that the preset target cell threshold is -61dBm, the cell qualities of cell 3, cell 5 and cell 6 are all greater than -61dBm. Therefore, the target cell includes cell 3 , cell 5 and cell 6 .

Optionally, in some embodiments, the preset value is the quality threshold of the target cell, and determining the target cell according to the measured measurement results of the N cells and the preset value includes: determining the target cell among the N cells according to the measurement event The adjusted cell quality of each cell; and the cell whose adjusted cell quality is greater than or equal to the preset target cell threshold is determined as the target cell.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the adjusted cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -61dBm and -59.5dBm respectively. Assuming that the preset target cell threshold is -61dBm, the cell qualities of cell 3, cell 5 and cell 6 are all greater than -61dBm. Therefore, the target cell includes cell 3 , cell 5 and cell 6 .

Optionally, in some embodiments, the preset value includes a value M ₁ , and determining the target cell according to the measured measurement results of the N cells and the preset value includes: determining M ₂ in the N cells N cells are the target cell, wherein the cell quality of any one of the target cells is not less than the cell quality of any one of the non-target cells, and the non-target cells include the N cells that do not belong to the target cell For a cell, M ₁ is a positive integer greater than or equal to 1, M ₂ is a positive integer greater than or equal to 1, and M ₂ is less than or equal to N and less than or equal to M ₁ .

Optionally, in some embodiments, the value M ₁ represents the number of cells included in the target cell. Optionally, in some embodiments, the value of M ₁ is greater than the value of N. In this case, the N cells are all the target cell. In other words, the value of _M2 is equal to N. In other embodiments, the value of M ₁ is less than the value of N. In this case, when determining the target cell, the cell qualities _of the N cells can be sorted from high to low, and the top M1 cells are the target cells.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -60dBm and -59.5dBm respectively. Assuming that the value of M ₁ is 3, the target cell includes 3 cells. The three cells are cell 3, cell 5, and cell 6, respectively.

However, in some cases, cells with tied cell quality may occur. For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -60dBm, -60dBm and -59.5dBm respectively. Assume that M1 takes _a value of 3. In this case, if the cell quality of the six cells is ranked from high to low, the cell quality rankings of cell 4 and cell 5 are equal, and both have the third highest cell quality. But the target cell only includes 3 cells. In this case, it may be determined that any one of cell 4 and cell 5 belongs to the target cell.

Optionally, in some embodiments, the value M1 represents the rank _of the cell quality in the target cell when the cell quality is sorted from high to low, if the rank of the cell quality of one of the N cells is higher than or equal to M ₁ , the cell belongs to the target cell.

In some embodiments, the value of M ₁ is greater than the value of N. In this case, the N cells are all the target cell. In other words, the value of _M2 is equal to N. In other embodiments, the value of M ₁ is less than the value of N. At this time, the value of _M2 may be equal to or greater _than the value _of M1. But the value of _M2 is smaller than the value of N.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -60dBm and -59.5dBm respectively. Assuming that the value of M ₁ is 3, the target cell includes 3 cells. The three cells are cell 3, cell 5, and cell 6, respectively. _In this case, the value of M1 is the same as that of _M2 .

As another example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -60dBm, -60dBm and -59.5dBm respectively. Assume that M1 takes _a value of 3. In this case, if the cell quality of the six cells is ranked from high to low, the cell quality rankings of cell 4 and cell 5 are equal, and both have the third highest cell quality. In this case, the target cell includes four cells, which are cell 3, cell 4, cell 5, and cell 6, respectively.

Optionally, in some embodiments, the preset value includes a value M ₁ , and determining the target cell according to the measurement results of each of the N cells and the preset value includes: determining The M ₂ cells of the target cell are the target cell, wherein the adjusted cell quality of any one of the target cells is not less than the adjusted cell quality of any one of the N cells except the target cell, M ₁ is A positive integer greater than or equal to 1, M ₂ is a positive integer greater than or equal to 1, M ₂ is less than or equal to N and less than or equal to M ₁ .

Optionally, in some embodiments, the value M ₁ represents the number of cells included in the target cell. Optionally, in some embodiments, the value of M ₁ is greater than the value of N. In this case, the N cells are all the target cell. In other words, the value of _M2 is equal to N. In other embodiments, the value of M ₁ is less than the value of N. In this case, when determining the target cell, the adjusted cell qualities _of the N cells may be sorted from high to low, and the top M1 cells are the target cells.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the adjusted cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -60dBm and -59.5dBm respectively. Assuming that the value of M ₁ is 3, the target cell includes 3 cells. The three cells are cell 3, cell 5, and cell 6, respectively.

However, in some cases, cells with adjusted cell qualities tied may occur. For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the adjusted cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -60dBm, -60dBm and -59.5dBm respectively. Assume that M1 takes _a value of 3. In this case, if the adjusted cell quality of the six cells is ranked from high to low, the adjusted cell quality rankings of cell 4 and cell 5 are equal, and both are the third highest cell quality after adjustment. But the target cell only includes 3 cells. In this case, it may be determined that any one of cell 4 and cell 5 belongs to the target cell.

Optionally, in some embodiments, the value M1 represents the ranking _of the adjusted cell quality in the target cell when the adjusted cell quality is sorted from high to low, if the adjusted cell quality of one of the N cells is If the ranking is higher than or equal to M ₁ , the cell belongs to the target cell.

In some embodiments, the value of M ₁ is greater than the value of N. In this case, the N cells are all the target cell. In other words, the value of _M2 is equal to N. In other embodiments, the value of M ₁ is less than the value of N. At this time, the value of _M2 may be equal to or greater _than the value _of M1. But the value of _M2 is smaller than the value of N.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the adjusted cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -60dBm and -59.5dBm respectively. Assuming that the value of M ₁ is 3, the target cell includes 3 cells. The three cells are cell 3, cell 5, and cell 6, respectively. _In this case, the value of M1 is the same as that of _M2 .

As another example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the adjusted cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -60dBm, -60dBm and -59.5dBm respectively. Assume that M1 takes _a value of 3. In this case, if the adjusted cell quality of the six cells is ranked from high to low, the adjusted cell quality rankings of cell 4 and cell 5 are equal, and both are the third highest cell quality after adjustment. In this case, the target cell includes four cells, which are cell 3, cell 4, cell 5, and cell 6, respectively.

In some other embodiments, the preset value may also include a value M ₃ , and the value M ₃ may represent the number of good beams included in the target cell or the ranking of the number of good beams from high to low. The specific implementation manner is similar to the implementation manner including the value M ₁ , which need not be repeated here.

Optionally, in some embodiments, the preset value may also include a value M ₄ . The target cells may be M ₄ cells that obtain measurement results first among the N cells, where M ₄ is a positive integer greater than or equal to 1. That is to say, in this case, there is no need to determine the measurement results of each cell, and the target cell can be determined as long as the measurement results of M ₄ cells are measured.

Optionally, the preset value may include the above content (that is, the _first preset value, the second preset value, the third preset value, the preset target cell threshold, the value M1, etc.) two or more. For example, the preset value may include the first preset value and the second preset value. As another example, the preset value may include the second preset value and the third preset value. For another example, the preset value may include the first preset value, the second preset value and the value M ₁ . I won't list them all here.

Optionally, in some embodiments, when the preset value includes two or more of the above contents, as long as a cell satisfies one of the two or more, the cell meets the preset condition .

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the adjusted cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -61dBm and -59.5dBm respectively. Assuming that the preset condition includes the first preset value and a value M1, the first preset value is -1dBm, and the value of M1 is ₃ . In this case, the cells satisfying the cell quality greater than -60dBm are cell 3 and cell 6. Although the cell quality of the cell 5 is less than -61dBm, the cell quality of the cell 5 ranks third (sorted from high to low). Therefore, cell 5 also belongs to the target cell. In this case, the target cell includes 3 cells. The three cells are cell 3, cell 5, and cell 6, respectively.

Optionally, in some other embodiments, when the preset condition includes two or more of the above contents, a cell meets the preset condition only when all the contents are satisfied.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. It is assumed that the adjusted cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -61dBm and -59.5dBm respectively. Assuming that the preset condition includes the first preset value and a value M1, the first preset value is -1dBm, and the value of M1 is ₃ . In this case, the cells satisfying the cell quality greater than -60dBm are cell 3 and cell 6. Although the cell 5 is the cell whose cell quality ranks third (from high to bottom), the cell quality of the cell 5 is less than -61 dBm. Therefore, cell 5 does not belong to the target cell. In this case, the target cell includes 2 cells. The two cells are cell 3 and cell 6, respectively.

103. Send the measurement result of the target cell to the base station.

Optionally, the measurement result of the serving cell of the terminal may also be sent to the base station.

Optionally, the measurement result of the first cell may also be sent to the base station.

It can be understood that the target cell may include the first cell, and when the target cell includes the first cell, the measurement result of the target cell sent to the base station already includes the measurement result of the first cell. The target cell may not include the first cell. In this case, the terminal will send the measurement result of the first cell to the base station in addition to the measurement result of the target cell. In a possible manner, no matter whether the target cell includes the first cell or not, the measurement results of the first cell may be included in different fields from the measurement results of cells other than the first cell in the target cell.

Optionally, the target cell may also include the serving cell. When the target cell includes the serving cell, the measurement result of the target cell sent to the base station already includes the measurement result of the serving cell. The target cell may also not include the first cell. In this case, the terminal will send the measurement result of the serving cell to the base station in addition to the measurement result of the target cell to the base station. In a possible manner, regardless of whether the target cell includes the serving cell or not, the measurement results of the serving cell may be included in different fields from the measurement results of cells other than the serving cell in the target cell.

The serving cell of the terminal may be the same as or different from the first cell.

Optionally, the target cell may include the serving cell and/or the first cell of the terminal.

In other words, in some cases, the serving cell of the terminal, the cell satisfying the trigger condition, and the target cell may be different cells. In other cases, two or all of the terminal's serving cell, the cell satisfying the trigger condition, and the target cell may be the same.

For example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. Assume that the cell qualities of the six cells are -62dBm, -61.5dBm, -59dBm, -64dBm, -60dBm and -59.5dBm respectively. Assume that cell 1 is a serving cell, and cell 2 is a cell that satisfies the trigger condition. Assume that the target condition includes the first preset value, and the first preset value is 2. In this way, the cell qualities of cell 3, cell 5, and cell 6 are all greater than -61 dBm. Therefore, the target cell includes cell 3 , cell 5 and cell 6 . In this case, the serving cell of the terminal, the cell satisfying the trigger condition, and the target cell are different cells.

As another example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. Assume that the cell qualities of the six cells are -62dBm, -61.5dBm, -59dBm, -64dBm, -60dBm and -59.5dBm respectively. Assume that cell 1 is a serving cell, and cell 3 is a cell that satisfies the trigger condition. Assume that the target condition includes the first preset value, and the first preset value is 2. In this way, the cell qualities of cell 3, cell 5, and cell 6 are all greater than -61 dBm. Therefore, the target cell includes cell 3 , cell 5 and cell 6 . In this case, the target cells include cells that meet the trigger condition.

As another example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. Assume that the cell qualities of the six cells are -62dBm, -61.5dBm, -59dBm, -64dBm, -60dBm and -59.5dBm respectively. Assume that cell 6 is a serving cell, and cell 3 is a cell that satisfies the trigger condition. Assume that the target condition includes the first preset value, and the first preset value is 2. In this way, the cell qualities of cell 3, cell 5, and cell 6 are all greater than -61 dBm. Therefore, the target cell includes cell 3 , cell 5 and cell 6 . In this case, the target cell includes the cell satisfying the trigger condition and the serving cell of the terminal.

As another example, assume that the value of N is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively. Assume that the cell qualities of the six cells are -62dBm, -61.5dBm, -57dBm, -64dBm, -60dBm and -59.5dBm respectively. Assuming that cell 3 is a serving cell, cell 3 is a cell that satisfies the trigger condition. Assume that the target condition includes the first preset value, and the first preset value is 2. Only the cell quality of cell 3 is greater than -59dBm. Therefore, the target cell, the cell satisfying the trigger condition, and the serving cell of the terminal are the same cell, that is, cell 3 .

Optionally, in some embodiments, the measurement result may also include the beam quality of each beam.

Optionally, the measurement result of the serving cell of the terminal, the measurement result of the cell meeting the trigger condition, and the measurement result of the target cell may be carried in one message. For example, a measurement report may be sent to the base station, where the measurement includes the measurement result of the serving cell carrying the terminal, the measurement result of the cell meeting the trigger condition, and the measurement result of the target cell.

Optionally, the measurement results of the serving cell of the terminal, the measurement results of the cell satisfying the trigger condition, and the measurement results of the target cell may be carried in different messages. For example, a first measurement report, a second measurement report, and a third measurement report may be sent to the base station, the first measurement includes the measurement result of the serving cell carrying the terminal, and the second measurement report carries the measurement result of the cell that meets the trigger condition , the third measurement report carries the measurement result of the target cell.

Optionally, in some embodiments, as long as one or more measurement results that need to be sent to the base station are determined, the determined measurement results may be sent to the base station.

Optionally, in some other embodiments, all measurement results may be sent to the base station together after all measurement results that need to be sent to the base station are determined.

It can be understood that the measurement result reported by the terminal can be used by the base station to guide the terminal to switch cells reasonably. Specifically, the base station may determine whether to switch the serving cell of the terminal according to the measurement result of the target cell. If it is determined that the serving cell of the terminal needs to be handed over, the target serving cell to which the terminal needs to be handed over may be selected according to the measurement result. For example, the base station may select the cell with the largest number of beams as the target serving cell to which the terminal needs to handover. In another example, the base station may select the cell with the best cell quality as the target serving cell to which the terminal needs to handover.

201. Determine N adjacent cells, where the N adjacent cells include a third cell and a cell whose absolute value of a difference between the cell quality and the third cell's cell quality is smaller than a cell quality preset value.

Specifically, the cell qualities of the M cells may be determined first, and then the maximum value Qmax among the M cell qualities may be determined. The cell of Qmax is the third cell. In other words, the third cell is a cell with the highest cell quality among the M cells. The terminal determines that among the M cells, the cell whose absolute value of the difference between the cell quality and the cell quality of the third cell is smaller than a cell quality preset value is the adjacent cell. M is a positive integer greater than or equal to N, and N is a positive integer greater than or equal to 1. For example, the value of M is 6. The six cells are cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6. It is assumed that the cell qualities of the six cells are -62dBm, -63.5dBm, -59dBm, -64dBm, -60dBm and -59.5dBm respectively. It can be seen that the cell quality of cell 3 is the maximum value of the six cell qualities. Assume the preset value is 2dBm. Therefore, the difference between -59dBm and 2dBm is -61dBM. It can be seen that the cell quality of cell 5 and the cell quality of cell 6 are both less than -61dBm. Therefore, cell 3, cell 5, and cell 6 are adjacent cells.

The average value of the K beams may be one of an arithmetic average value, a geometric average value, a weighted average value, and the like, which is not limited in this embodiment of the present application. If the number of beams whose beam quality is higher than the preset threshold in a certain cell is less than K, then the average value of the beam qualities of all beams in the cell is the cell quality of the cell.

Optionally, in some other embodiments, an average value of beam qualities of K beams in a cell whose beam quality is higher than a preset threshold may be determined, and then layer 3 filtering is performed on the average value. The value obtained after layer 3 filtering is the cell quality of the cell. The threshold and the value of K may be sent by the base station to the terminal through measurement configuration. The threshold value and the value of K may also be preset. The average value of the K beams may be one of an arithmetic average value, a geometric average value, a weighted average value, and the like, which is not limited in this embodiment of the present application. If the number of beams with beam quality higher than the preset threshold in a certain cell is less than K, then the average value of the beam quality of all beams in the cell is filtered by layer 3, which is the cell quality of the cell.

Optionally, in some other embodiments, the cell quality in the embodiment shown in FIG. 2 may also refer to a ranking (ranking) value. The ranking value of the serving cell and the ranking value of the neighboring cell can be determined according to the following formula:

Rs=Qmeas,s+Qhyst, (Formula 2.1)

Rn=Qmeas,n–Qoffset, (Formula 2.2)

Among them, Rs represents the ranking value of the serving cell, Rn represents the ranking value of the neighboring cell, Qmeas,s and Qmeas,n are the cell quality of the serving cell and the cell quality of the neighboring cell, respectively, Qhyst represents the hysteresis value, and Qoffset represents the offset. Qoffset may be a cell-level offset, or a frequency-level offset, or a cell-level offset plus a frequency-level offset. Qmeas,s and Qmeas,n may be the cell quality obtained according to the above method (that is, the average value of K beam qualities or the value obtained after the average value of K beam qualities is filtered by layer 3).

It can be understood that, before step 201, the measurement process needs to be started. Optionally, in some embodiments, the measurement process can be started according to the current standard. For example, for frequency layers and systems with higher priority than the serving cell, always measure the cells in these frequency layers and systems; if the level value calculated during the cell selection/reselection process of the serving cell is less than or equal to the first preset level value, then determine to start the measurement of the cell with the same frequency as the serving cell; if the level value calculated during the cell selection/reselection process of the serving cell is less than or equal to the second preset level value or not configured For the second preset level value, it is determined to start the frequency with the same priority as the frequency of the serving cell or the frequency with a priority lower than the frequency of the serving cell and the measurement of the cells in the system.

For example, the cell with the largest number of good beams among the N adjacent cells may be determined. If the serving cell is included in the cell with the largest number of good beams among the N adjacent cells, it can be determined to reside in the serving cell; if the cell with the largest number of good beams among the N adjacent cells does not include the serving cell, Then it is determined not to camp on the serving cell.

As another example, the number of good beams included in the serving cell may be compared with the number of good beams in cells other than the serving cell among the N adjacent cells, and if it is determined that the number of good beams included in the N adjacent cells is greater than If the number of good beams in the serving cell is determined not to reside in the serving cell; if it is determined that the N cells do not include a cell whose number of good beams is greater than the number of good beams in the serving cell, then determine to reside in the serving cell The serving cell.
